A problem occurs when i use function to update a bom line

Question

this is my first time to ask for help here. i am from china. hope to find a solution for my problem here.
here is my problem:
what i need is to update a bomline. this is my way: delete the old bomline and add a new one. the update operation is successful.
but it leads to another problem: some data in CA03 lost. for example: operation, sequence, backflushing, create on, create by, valid from.
so i think the data loss happens when i delete a bomline.
here is my solution:
before deleting a bom line. get the lost data and save it in memory.
after add a new bom line. update the data in CA03.
how about it? any better ideas?
if it is a good way , i do not know where to get the data i want.which table or which funtion? and use which BAPI to update the data in ca03
i realy appreciate it if you provide any suggestion

This is common to people using Windows.  You need to disable all firewall, antivirus, and antimalware programs.
